Lee Kwang Soo is returning for the season (he skipped s2) and the rest of the cast hasn't changed. Only Ahn Jae Wook won't be in s3.
The best cast with the best chemistry I can't wait! I'm glad Lee Seunggi also returned. He was hilarious in s2!
The rest of the cast members are: Yoo Jae Suk, EXO's Sehun, Park Min Young, gugudan's Kim Sejung and Kim Jong Min.
